Short answer
In skincare, "copper peptides" almost always means GHK-Cu (glycyl-L-histidyl-L-lysine with copper) in leave-on creams or serums. It is studied as a cosmetic signal ingredient for the look of firmness and repair-related pathways — not as an FDA-approved drug for disease. That is different from home-mixed or clinic injectable GHK-Cu, which this site treats as a research-chemical risk conversation. Peptide Confessions does not publish dosing, timing, injection or sourcing guidance.
Skincare copper peptides vs other topical peptides
Compare with Matrixyl (palmitoyl pentapeptide-4) for fine lines, and with peptides vs retinol. Hair-specific claims belong on copper peptides for hair.
